Definitions

  • the invention relates to an air springs and in particular to an air spring in which the end plate which is mounted opposite of the piston is formed integrally as a one-piece plastic member combining the end plate with a mounting bracket which is hollow to form an auxiliary fluid chamber. More particularly, the invention relates to such a combination end plate and mounting bracket which is mounted to a supporting structure which is oriented perpendicular to the direction of orientation of the corresponding structure on which the piston is mounted.
  • EP-A-0 264 573 discloses an air spring including an end cap member and an opposed piston member.
  • the piston member has a generally cylindrical side wall terminating in an upper open end and having an exterior annular clamping surface formed with a plurality of grooves.
  • the end cap member has a cup-shaped configuration with a cylindrical side wall terminating in a closed end wall and an open end which communicates with the interior of flexible sleeve.
  • Air actuators and in particular air springs consist of a pair of spaced end members and an intervening flexible sleeve or bellows formed of an elastomeric material to form an internal pressurized fluid chamber. These devices are used for many applications. One main applications is between spaced components of a vehicle for absorbing road shock or supporting parts of machinery and equipment on which shock forces are continually imparted, and for regulating and maintaining the spacing between the two spaced components of various pieces of equipment including vehicles.
  • These air springs usually consist of an upper end member or end plate which is usually attached to the underside of a bracket or support member, and an opposite piston member which is usually mounted to the top surface of a second supporting structure spaced from the first supporting structure.
  • Patent No. 5,326,082 shows one type of air spring in which an auxiliary chamber is formed within the interior of the piston member as well as within the interior of the end cap or end member, both of which are formed of a plastic material to reduce corrosion and facilitate the production of the end members.
  • the mounting surfaces are parallel to each other and no structure is provided for securing one of the end members, and in particular the end member opposite of the piston, to a mounting surface perpendicular to that of the piston mounting surface.
  • the object of the invention is to provide an air spring which can be mounted to a structure extending perpendicularly to the mounting surface of the opposite structural member on which the piston is mounted, and which has an increased internal volume of the fluid chamber while not substantially increasing the size of the air spring.
  • Fig. 1 shows the integral bracket and end mounting plate of the present invention incorporated within an air spring or air actuator indicated generally at 1.
  • Air spring 1 has a pair of end members, one of which is a piston 2 which is mounted in an upright position on a support plate 3.
  • Support plate 3 could be mounted on the end of a trailing arm, axle plate or similar portion of a vehicle, or any spaced support structures of a piece of equipment with which air spring 1 can be used.
  • the unique bracket and end mounting plate combination of the present invention is indicated generally at 5, and is shown secured to one open end of a flexible sleeve or bellows 6, usually formed of an elastomeric material, which forms an internal fluid pressure chamber 7 (Fig. 2).
  • Combination 5 is shown mounted to a vertical side or web wall 9 of a U-shaped beam 10, which could be one of the chassis frame members of a vehicle.
  • Beam 10 could be other types of supporting structures of a vehicle or other equipment, but in accordance with one of the features of the invention, it will have a mounting surface such as web wall 9, which generally aligns with the longitudinal axis 11 of air spring 1 and perpendicular to the mounting surface 12 of support plate 3 on which piston 2 is mounted.
  • Fig. 2 shows in more detail the structure of the end mounting plate and bracket 5 of the present invention.
  • the end plate portion of combination 5 is indicated generally at 13, and has an annular disc-shaped configuration and is formed with a stepped outer peripheral flange 14.
  • a pressure clamp 15 sealingly clamps bead area 16 of sleeve 6 against flange 14 to form a fluid tight sealing engagement with the end plate.
  • End plate 13 further includes a generally semi-circular shaped planar wall 18 (Figs. 2 and 7), and a generally semi-circular shaped opening 19.
  • Bracket portion 22 of the bracket and end mounting plate combination 5 includes a generally planar upstanding wall 23 which has a somewhat triangular-shaped configuration as shown in Fig. 3, and which includes a plurality of spaced parallel reinforcing ribs 24 formed integrally on its outer surface and extending throughout the vertical length thereof.
  • a half dome-shaped enclosure wall 26 together with upstanding wall 23 forms an auxiliary air chamber 27 which is located above end plate 13 and in fluid communication with main pressure chamber 7.
  • a plurality of ribs 25 extend along the inside surface of wall 23 and continue along the inside surface of enclosure wall 26 (Figs. 2, 6 and 7) within fluid chamber 27.
  • a plurality of reinforcing ribs 29 and 30 also extend along the top and bottom surfaces, respectively, of semi-circular wall 18 of end plate 13 to provide for an extremely strong and rigid mounting bracket and end plate structure.
  • a pair of mounting bosses 31 are formed integrally with upstanding wall 23 and portions of enclosure wall 26 for securing bracket and end mounting plate 5 to flange wall 9 (Figs. 1 and 6).
  • Bosses 31 preferably are formed with a hollow bore 33 through which bolts 34 extend for clamping wall 23 tightly against wall 9 by a nut 35 and a rear retaining washer 36.
  • Other types of attachment means and fasteners can be used for securing wall 23 generally flush against wall 9 than bolts 34 shown in the drawings.
  • a rigid conduit 38 is formed integrally with planar wall 23, preferably adjacent upper end 39 of wall 23 where it merges with enclosure wall 26.
  • Conduit 38 has a hollow bore 40 and is adapted to be connected to a fluid supply line 41 which is connected to a compressor or other fluid pressure device for regulating the flow of air into and out of fluid chambers 7 and 27.
  • Fluid supply line 41 may be secured to conduit 38 by a clamp ring 43, and preferably a plurality of O-rings 44 provide sealing engagement between conduit 38 and fluid supply line 41.
  • Conduit 38 preferably extends through an opening 42 formed in web wall 9.
  • Combination end plate and mounting bracket 5 preferably is formed of a high strength plastic material, or other types of lightweight materials which are well known in the air spring industry to provide for a corrosion resistance structure.
  • the improved integral bracket and end mounting plate for air spring is simplified, provides an effective, safe, inexpensive, and efficient device which achieves all the enumerated objectives, provides for eliminating difficulties encountered with prior devices, and solves problems and obtains new results in the art.
